Executive director of the Domar Center for Mind/Body Health. A pioneer in the application of mind/body medicine to women's health issues, she's an assistant clinical professor of obstetrics, gynecology, and reproductive biology at Harvard Medical School.

"Often I seem to worry about things that are very unlikely to happen," says Domar. "I put a loved one on the plane and think, 'Is it going to get hijacked? Will it crash?' And I go down the list of all the awful things that could happen. So I use a technique called 'thought stopping': I recognize this is totally unrealistic and don't allow my brain to go down that road." When Domar is feeling tense, she gives the people around her a heads-up about her vulnerabilities; she lets them know ahead of time that her frustrations are not aimed at them. "The fact is, if you get angry with someone close to you, they're likely to assume it's their fault or feel the need to defend themselves," she says. And in situations where she has been overwhelmed—such as when she learned that her mother had terminal cancer—the first thing she does is to think about what she needs in the moment. "Then I write down all the resources and coping skills I have," she says. "And I remind myself of who I can count on during a crisis."
